[QUOTE=Ashley] Sounds like exactly the problem everyone else has been having with Dropbox. It's a pretty unreliable host right now, it seems.[/QUOTE]

Hmm, that's how I was planning to host it. Do you know of any other cheap/free ways to host them? I use Tumblr as my website and have it all set up the way I want it. But I'm fairly certain you cant host files on there.

You can't realistically host games on Dropbox or Google Drive for broad distribution anyway, because they have fairly low bandwidth limits (they're intended for personal use). Just look for a cheap website host, there are loads and the prices are pretty low.

I was struggling with making this file sharing your game thing work as well. The problem, I found (for me, at least - black screens only) was that I hadn't followed the Dropbox tutorial exactly as described. I thought, because I had selected enable public sharing on the folder and files in Dropbox that that would be enough. It turns out that you still need to formally set up a Public folder - click on the link in the tutorial (duplicated below) to enable full access to the index file. I hope this helps...
